This is what is in the Build tab: image-2022-04-22-062801040 — ImgBB[^]
This code lives on a VM that was migrated into a zero trust cloud. I can go back to the original VM, and 2015 there has the full build menu.

As I recall, Visual Studio has never supported working with solutions that are located on network/remote drives.
Are you working with Visual Studio on the virtual machine where the solution resides?

No, I just RDP into it. Nothing too fancy.

A STL container is not your typical c++ class, how do you declare a vector pointer and pass it to a function.
class someclass
{
public:
int ID;
}
void somefunction(vector<someclass>* vec)
{
someclass scitem;
vec->push_back(scitem);
}
vector<someclass>* vec;
somefunction(vec);
I`m also not sure how a vector of pointers would work.
void somefunction(vector<someclass>* vec)
{
someclass * scitem;
scitem = (someclass*)malloc(sizeof(someclass));
vec->push_back(scitem);
}
vector<someclass*>* vec2;
somefuntion(vec2);

Yes, STL containers are just template classes and can be manipulated the same as any class objects. And as such, a vector may contain objects, or pointers to objects. But remember in the second case that the items pointed to, must not be removed while the vector still owns them.
std::vector<char*>* pMyvec = new std::vector<char*>(); pMyvec->push_back("A string");
pMyvec->push_back("Another string");
int result = myfun(pMyvec);
BTW you should not use malloc in C++ code, as new and delete is the correct way to manage memory.

Quote: And as such, a vector may contain objects, or pointers to objects
But when you add a class object, the vector doesn`t make a copy of the object, it creates a pointer to the object being added. A linked list deals with pointers not objects.

If you add an object to an STL container (vector, list, set, map...), the object is copied into the container. The objects must all be of the same type, however. The only way to put polymorphic objects into a container is to use a container of pointers to their common base class, in which case the objects need to survive outside the container, probably by having been allocated from the heap.

thanks Greg, I`ll keep that in mind.

No, the vector copies whatever type you have declared it with. For example:
std::vector<std::string> myVec;
std::string newstr = "A string";
myVec.push_back(newstr);

Well sometimes it does; but what has that to do with this question?

ok, I think I get your point

You are trying to dereference the BDADDR_ANY structure. You should just take the value, which is already the address.
loc_addr.rc_bdaddr = BDADDR_ANY;

Your code compiles fine on my Linux box (GCC 9.4).

It is .Net:
Microsoft Development Environment 2003 Version 7.1.3088.
Microsoft .Net Framework 1.1 Version 1.1.4322
Visual C++ MFC:
When I add to References System.DirectoryServices.dll it refuses to add not 1.1.4322 version of it,
only System.DirectoryServices.dll of 1.1.4322 version
|
|
|
|
|
.Net is for managed C++/CLI.
MFC does nt support "managed" code, only the native one. So you have to create a new C++/CLI project and try to work with this DirectorySearcher class in there.
|
|
|
|
|
Can you think about the problem to implement the use of DirectorySearcher class?
I have System.DirectoryServices.dll suitable exactly for my version of Microsoft .Net Framework 1.1 Version 1.1.4322.
Other versions of System.DirectoryServices.dll are refused to be added to the References folder in the project.
About to upgrade software that will be suitable to new Visual Studio version - it not so simple.
It is huge old software. I has performed conversion today but can not yet to see the result today. There were errors that conversion raised during it

Plus, let's not forget the "bible" of native/managed interop, C++/CLI in Action[^] by our friend Nish.
The difficult we do right away...
...the impossible takes slightly longer.
